Dharmarajan Heads Home to India

A group of twelve adults, including Dharmarajan, stands outdoors in front of trees and a wooden cabin in India, posing for a group photo on a sunny day.

For over five years, SREL was fortunate to have Guha Dharmarajan, an expert in disease ecology, on its faculty. As the year 2021 counted down, Dharmarajan, who was an assistant research scientist at the lab, packed up his office and his belongings to head home to India.

Impact in the lab and in the field

Dharmarajan investigated vector-borne diseases. He examined the interactions of Asian tiger mosquitos with avian malaria in birds, opossum spatial ecology and rabies in raccoons.

In addition to bringing a unique skill set to the lab, Dharmarajan enriched the lives of his students — David Bernasconi, Wes Dixon, Pooja Gupta, Erik Neff, and Manette Tanelus.

Gupta, a bioinformaticist at the Utah Public Health Laboratory in Salt Lake City, began as a doctoral student at SREL in 2016. She studied avian malaria in the tropical sky-islands of the Western Ghats, India. Gupta describes her learning experience under Dharmarajan as all-encompassing.

“I learned how to order things, set up the lab, and train technicians.” Gupta said. “ It was a great experience for me.”

David Bernasconi, a research data coordinator at the Pacific States Marine Fisheries Commission in Idaho, began working at the lab in 2016. He became a master’s student under Dharmarajan the following year. Bernasconi said he experienced a tremendous amount of growth working with Dharmarajan.

“My time with Guha at SREL was probably one of the more informative periods of my adult life. From a professional standpoint, I grew substantially. Many of the skills he imparted to me, I still use today. In particular, when presenting to research partners, he made sure that I had the data ready and summarized to answer any question,” Bernasconi said. “I carry this level of preparation into meetings with stakeholders every day. It’s benefited me substantially.”

Dixon was also a master’s student under Dharmarajan. Starting at SREL in 2018, he had an opportunity to conduct research that maximized wildlife surveillance techniques to improve management of disease outcomes.

“The experiences and skills I learned working with Guha Dharmarajan have been invaluable. Before I arrived at the lab, I had never worked with needles, chemically immobilized animals, or trained other people,” said Dixon. “It’s a cool feeling to have so many new skills pertinent in my field.”

Erik Neff, who began the same year as Dixon, studied mosquito ecology and evolution. Working on his M.S. degree, he focused on the mosquito-canine heartworm system. Neff attributes Dharmarajan with preparing him for his current role as the chief scientific officer at Fluker’s Cricket Farms in Port Allen, Louisiana.

Presently at Virginia Tech, Tanelus spent the summer of 2017 at SREL in the NSF’s Research Experience for Undergraduate Program and later returned to the lab to work. Dharmarajan inspired her to pursue a career in infectious diseases.

“As an undergraduate student and technician in Guha’s lab, I learned a lot about mosquitoes, parasites and arthropod-borne pathogens,” Tanelus said. “He wrote a letter of recommendation for me, which led me to the lab where I will be pursuing my Ph.D. Guha has made an incredible impact in the lives of many students.”

SREL’s former disease ecologist is delighted the lab will continue research in disease ecology.

Future plans

Traveling with his pet cat in tow, a new journey is truly beginning for Dharmarajan. After he and the cat get over jet lag (that might take a while), he has no plans to rest. His plans are to teach and conduct research at a small liberal arts college near his family in India.

“It’s been a great ride working with my graduate students and technicians, but I had to reassess what is important because of COVID-19,” he explained. “I wanted to be closer to my family, if they should need me.”

In addition to its research activities, SREL conducts a number of educational and outreach programs, many of which inform SRS-area residents of the activities on the former nuclear site and the environmental impacts of those activities.

We, at SREL, have high hopes for collaborative research opportunities with Savannah River National Laboratory under its new management and vision for the Department of Energy. Excitedly, we also look forward to potential collaborations with our colleagues at UGA and other universities.

“Because they are really large birds, they can’t get off the ground as easily as smaller birds. They rely on the earth’s surface heating up to produce a thermal current. They can use those currents flowing around them to lift them up,” he said. “Landscape changes like paved roads wi

Kojima and Oswald awarded Fellowships

A woman with straight shoulder-length hair and a blue sweater smiles at the camera indoors, with blurred people and shelves—perhaps at a Kojima Fellowships event—in the background.

Laura Kojima, a master’s student at SREL and the Odum School of Ecology, is the recipient of a 2021 National Science Foundation Graduate Research fellowship. The fellowship will provide a stipend for up to three years and additional funds to directly support her research.“Receiving this fellowship is a huge honor, especially as an underrepresented minority in STEM. The process of grant writing and conducting my own research was a completely new process for me, and to have the mentorship and accessibility to successfully do so is something I am very grateful for,” said Kojima.

Kojima’s research assesses levels of chemical contaminants in alligator tail muscle and exposure concerns associated with the public harvest and consumption of alligators that travel on and off contaminated areas.

Scott Oswald, a doctoral student at SREL and the Warnell School of Forestry and Natural Resources, was recently named a recipient of the 2020 Office of Science Graduate Student Research fellowship from the U.S. Department of Energy.

The award is given for outstanding accomplishments in academics and research that show the potential to make important contributions to the mission of the DOE Office of Science. The fellowship will allow Oswald to conduct research at the Oak Ridge National Laboratory in 2022.

Oswald’s research will work to improve how large ecosystem models represent sugar and starch dynamics to better predict how plants respond to future climates, and to develop a framework for those dynamics using ecological and evolutionary theory.

“This fellowship is a good opportunity to receive mentorship and guidance about developing the ability to make connections between my background in mathematical biology and experimental observations,” said Oswald.
